GENERAL POWER TOOL SAFETY WARNINGS
WARNING:
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1)Work area safety
a)Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b)Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust.
Power tools create sparks which may ignite
the dust or fumes.
c)Keep children and bystanders away while
operating a power tool.
Distractions can cause you to lose control.
2)Electrical safety
a)Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed
(grounded) power tools.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
b)Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.
There is an increased risk of electric shock if
your body is earthed or grounded.
c)Do not expose power tools to rain or wet
conditions.
Water entering a power tool will increase the
risk of electric shock.
d)Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts.
Damaged or entangled cords increase the risk
of electric shock.
e)When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
f)If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply.
Use of an RCD reduces the risk of electric shock.
3)Personal safety
a)Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the influence of drugs, alcohol or
medication.
3
English
A moment of inattention while operating
power tools may result in serious personal
injury.
b)Use personal protective equipment. Always
wear eye protection.
Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing
protection used for appropriate conditions
will reduce personal injuries.
c)Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool.
Carrying power tools with your finger on the
switch or energising power tools that have
the switch on invites accidents.
d)Remove any adjusting key or wrench before
turning the power tool on.
A wrench or a key left attached to a rotating
part of the power tool may result in personal
injury.
e)Do not overreach. Keep proper footing and
balance at all times.
This enables better control of the power tool
in unexpected situations.
f)Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts.
Loose clothes, jewellery or long hair can be
caught in moving parts.
g)If devices are provided for the connection of
dust extraction and collection facilities,
ensure these are connected and properly
used.
Use of dust collection can reduce dust-related
hazards.
4)Power tool use and care
a)Do not force the power tool. Use the correct
power tool for your application.
The correct power tool will do the job better
and safer at the rate for which it was designed.
b)Do not use the power tool if the switch does
not turn it on and off.
Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
c)Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools.
Such preventive safety measures reduce the
risk of starting the power tool accidentally.
d)Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e)Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use.
Many accidents are caused by poorly
maintained power tools.
f)Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g)Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed.
Use of the power tool for operations different
from those intended could result in a
hazardous situation.
5)Battery tool use and care
a)Recharge only with the charger specified by
the manufacturer.
A charger that is suitable for one type of
battery pack may create a risk of fire when
used with another battery pack.
b)Use power tools only with specifically
designated battery packs.
Use of any other battery packs may create a
risk of injury and fire.
c)When battery pack is not in use, keep it away
from other metal objects like paper clips,
coins, keys, nails, screws, or other small
metal objects, that can make a connection
from one terminal to another.
Shorting the battery terminals together may
cause burns or a fire.
d)Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery
may cause irritation or burns.
6)Service
a)Have your power tool serviced by a qualified
repair person using only identical
replacement parts.
This will ensure that the safety of the power
tool is maintained.

OPERATION
1. Mounting the blade
This unit employs a detachable mechanism that
enables mounting and removal of saw blades
without the use of a wrench or other tools.
(1) Turn on and off the switching trigger several times
so that the lever can jump out of the front cover
completely. Thereafter, turn off the switch and
remove the battery. (Fig. 6)
How to make the batteries perform longer
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the
electric current, the battery may be damaged and
its life will become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a while.
CAUTION

used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes rest
until the next charging.
●
<For UC18YRSL>
If the battery is rechraged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
may light in green.
The battery will not be recharged. In such a case,
let the battery cool before charging.
●
<For UC18YGSL>
If the battery is charged while it is heated because
it has been left for a long time in a location subject
to direct sunlight or because the battery has just
been used, the pilot lamp of the charger lights for
1 second, does not light for 0.5 seconds (off for

WHEN THE BLADE IS BROKEN
Even when the saw blade is broken and remains
inside the small slit of the plunger, it should fall out
if you push the lever in the direction of the arrow
mark, and face the blade downward. If it doesn’t fall
out itself, take it out using the procedures explained
below.
(1) If a part of the broken saw blade is sticking out of
the small slit of the plunger, pull out the protruding
part and take the blade out.
(2) If the broken saw blade is hidden inside the small
slit, hook the broken blade using a tip of another
saw blade and take it out. (Fig. 12)

NOTE:
Continued use of the tool without cleaning and
lubricating the area where the saw blade is installed
can result in some slack movement of the lever due
to accumulated sawdust and chips.
Under the circumstances, pull a rubber cap provided
on the lever in the direction of an arrow mark as
shown in Fig. 14 and remove the rubber cap from
the lever. Then, clean up the inside of the blade
holder with air and the like and carry out sufficient
lubrication.
4. Confirm that the battery is mounted correctly.
The rubber cap can be fitted on if it is pressed firmly
onto the lever. At this time, make certain that there
exists no clearance between the blade holder and
the rubber cap, and furthermore ensure that the saw-

CAUTION:
Avoid carrying it with your finger on the switch. A
sudden startup can result in an unexpected injury.
Be careful not to let sawdust, earth, moisture, etc.,
enter the inside of the machine through the
plunger section during operation. If sawdust and
the like accumulate in the plunger section, always
clean it before use.
Do not remove the front cover (refer to Fig. 6).
Be sure to hold the body from the top of the front
cover.
During use, press the base against the material
while cutting.
Vibration can damage the saw blade if the base is
not pressed firmly against the workpiece.
Furthermore, a tip of the saw blade can sometimes
contact the inner wall of the pipe, damaging the
saw blade.
Select a saw blade of the most appropriate length.
Ideally, the length protruding from the base of the
saw blade after subtracting the stroke should be
larger than the material (see Fig. 18 and Fig. 20).
If you cut a large pipe, large block of wood, etc.,
that exceeds the cutting capacity of a blade; there
is a risk that the blade may contact with the inner
wall of the pipe, wood, etc., resulting in damage.
(Fig. 19, Fig. 21)
To extend the lifetime, the lithium-ion battery
equips with the protection function to stop the
output. Therefore, if the tool is overloaded, the
motor may stop. However, this is not the trouble
but the result of protection function. In this case,
release the switch of tool and eliminate the causes
of overloading.

MAINTENANCE AND INSPECTION
CAUTION:
Pull out battery before doing any inspection or maintenance.
1. Inspecting the blade
Continued use of a dull or damaged blade will result
in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with a
new one as soon as excessive abrasion is noted.
2. Check the Screws
Loose screws are dangerous. Regularly inspect them
and make sure they are tight.
CAUTION:
Using this power tool with loosened screws is
extremely dangerous.
3. Maintenance of the motor
The motor unit winding is the very “heart”’ of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
